What E24 usually means
E24 usually means the dishwasher detected a drain problem.
Codes can vary by exact Bosch dishwasher model number, production year, and regional design. Use this as first-pass guidance, then confirm the model-specific manual or manufacturer support page before opening panels or replacing parts.
First checks
Clean the accessible filter area, check the sink drain, and inspect the visible drain hose routing under the sink.
A blocked filter, kinked hose, closed disposal knockout, or slow household drain can all create an E24 symptom.
- Clean the filter according to the manual.
- Check the air gap if installed.
- Inspect the visible drain hose.
- Run one short drain test.
When to stop
Stop if E24 returns after the visible drain path is clear or if water leaks from the cabinet area.
Keep the full model number, exact E24 display text, cycle name, and timing ready before contacting Bosch support or a qualified technician.
Model numbers affected
Commonly searched model families include built-in dishwashers, front-control dishwashers, top-control dishwashers, and compact dishwashers.
This is not a confirmed model-number list. Match the exact code to the full model number on the appliance tag before ordering parts, opening panels, or booking service.
